Pregnancy week 24 brought plenty of ups and downs. My nausea has started creeping back in, especially when I’m not intentional about eating every few hours, so I’m sharing the easy snacks that have been helping me stay fueled when food does not sound particularly exciting.

I’ve also been extra tired, sick, and navigating new information about my body. I had my labs checked this week and talk about why I believe iron status should be monitored more than once throughout pregnancy, especially for pregnant athletes.

After weeks of resting my back, the aching has started to improve, and I finally got the results of my MRI. I have inflammation around my SI joints and within the bone, which means I need to be thoughtful about how I approach movement for the remainder of pregnancy.

I have been given the yellow light to run, not a full green light. Now I’m working through what that means, reaching out to a physical therapist, and creating a plan that allows me to keep moving without ignoring what my body is telling me.

This week, I will finally get my MRI after taking a complete break from running and lifting. While I wait for answers, I’m walking and slowing down.

I also had an emotional pelvic-floor moment when I peed myself after sneezing while holding something heavy. It had never happened before, and it immediately made me worry about what it meant for my pelvic floor and my future as a runner.

The nausea is back, my stomach feels crowded, and almost nothing sounds good to eat. I talk about how I’m relying on cues beyond hunger to remind myself that my body and baby still need consistent nourishment, even when my appetite is nowhere to be found.

I also reflect on my first postpartum experience, when I felt desperate to start moving again as quickly as possible. This time, I feel less pressure to rush postpartum, but I’m still confronting a deeper fear: that I’m running out of time to achieve my running goals.

Resting right now has brought that fear straight to the surface. In this episode, I talk honestly about losing fitness, allowing recovery, and learning that slowing down does not mean my goals are disappearing.

In this week’s pregnancy update, I’m combining weeks 21 and 22 and sharing what it has been like to navigate ongoing lower back and butt pain while pregnant.

After dealing with this pain for about a year and seeing different PTs, I finally booked an appointment with sports medicine, where they brought up the possibility of a sacral stress fracture. Now I’m waiting to get an MRI approved so we can figure out what is actually going on.

I talk about how hard it is to rest when you don’t have answers yet, especially when running is such a big part of how I feel like myself. It has been 17 days since my last run, and I’m processing the grief, frustration, and comparison that comes with that. During my first pregnancy, I ran until my due date, so this experience feels very different.

In this episode, I also talk about comparing myself to other pregnant runners, ordering a belly band to hopefully help with possible SI pain, the excitement of our anatomy scan, ongoing lightning crotch and pelvic heaviness, feeling more tired, nausea creeping back in, and finding a little bit of sanity through deep breathing core exercises.

This is your reminder that taking time off from running, resting, or changing your workouts does not mean you won’t come back. Sometimes the strongest thing we can do is listen, adapt, and let our body tell us what she needs.

At 20 weeks pregnant, the bump is officially bumpin’ and I’m fully living in pregnancy clothes now. In this episode, I’m sharing how renting maternity clothes through Nuuly has helped my body image by making it easier to dress my changing body in clothes that actually fit and feel cute.

I also talk about how training is going right now: running still feels good, but I am definitely slower. And even when you know slowing down during pregnancy is normal, it can still be mentally hard when your pace doesn’t match what you’re used to seeing.

I also share an update on some mild back pain, what my pelvic floor PT said about it, and how my sugar cravings have improved since I started prioritizing high-protein snacks.

This episode is for the pregnant runner who is navigating body changes, pace changes, craving changes, and trying to keep showing up for herself without expecting her pregnant body to perform like her pre-pregnancy body.

This week, the belly officially popped and I am feeling very pregnant in the cutest way. Running and workouts are still feeling good and comfortable, but I am definitely slowing down, which is a very normal part of training through pregnancy.

I’m also talking about sugar cravings this week, not from nausea or food aversions this time, but from that very real “I could eat dessert for every meal” kind of vibe. And for pregnant athletes, cravings can sometimes be a helpful cue that we may not be eating enough overall. If you’re running, lifting, growing a human, and trying to get through your day, your energy needs are not exactly giving “light snack and vibes.”

In this episode, I’m sharing why meal planning and prepping can be such a helpful tool for pregnant runners, especially when your appetite, schedule, and energy are all changing. We’ll talk about how to make sure you’re getting enough calories, carbs, protein, and nutrient-dense foods without making eating feel like another full-time job.

I also went to pelvic floor physical therapy this week, so I’m sharing what we talked about, what I’m paying attention to, and why pelvic floor support can be such a game changer for pregnant athletes.

 In this combined pregnancy update for weeks 16–18, I’m sharing a much heavier season of life. My dad was placed on hospice and passed away during these weeks, and navigating grief while pregnant felt surreal and overwhelming. I talk honestly about what it looked like to simply survive during this time, letting exercise go for a while, and how emotional stress can change your relationship with movement and self care.

I also share how it felt returning to exercise after time away, the physical symptoms that started popping up this pregnancy that I didn’t experience with my first, including back pain, pelvic floor heaviness, and lightning crotch (WHY does no one prepare us for that name?!). And in the middle of all the heartbreak, there were still beautiful moments too, like seeing baby kick from the outside for the first time.

This episode is raw, vulnerable, and a reminder that pregnancy doesn’t happen in a vacuum. Life keeps life-ing, and sometimes the goal is simply getting through the day with compassion for yourself.

This week officially felt like a turning point. I’m just loving how amazing it feels AMAZING to enjoy food again and actually feel hungry. I share what’s been different physically this week, including why I think I may have started feeling baby kicks for the first time.

I also open up about something heavier going on behind the scenes. My dad has been sick, and balancing pregnancy, motherhood, work, and family stress has made self care feel really hard lately. We talk about what it looks like to try your best during seasons where life feels emotionally overwhelming.

And yes… we’re also talking boobs. 😂 I share how drastically my chest changed during my first pregnancy, why I switched to nursing bras while still pregnant, and the sports bra that actually worked for running after trying what felt like 7 million options.

If you’re pregnant and navigating the weird mix of excitement, exhaustion, body changes, gratitude, and stress all at once… this episode will probably make you feel a little less alone.

Week 14 and things are finally shifting.

After weeks of nausea, food aversions, and just trying to get through the day, I’m officially feeling hungry (LIKE SO HUNGRY!) again… and honestly? It feels amazing.

In this episode, I’m sharing what changed this week as I move into the second trimester, including:

I also open up about something that doesn’t get talked about enough: getting weighed at doctor’s appointments.

During my first pregnancy, I chose not to see my weight because I knew it could negatively impact my mental health. In this episode, I break down:

Because you deserve to feel informed, respected, and in control of your body throughout pregnancy.

Week 13 and officially in the second trimester… but honestly? It’s giving first trimester energy 😅

In this episode, I’m sharing the real behind-the-scenes of this week: navigating more reflux (earlier than last pregnancy), waves of nausea and food aversions that finally eased up, and that craving for the elusive “second trimester bliss.”

On the bright side, I ran a half marathon this week (!!) and felt strong, fueled, and proud. I’m walking you through how I approached carb loading during pregnancy, how the race actually felt in my body, and what signs I pay attention to when deciding if my training is supportive… or too much.

I also dive into a question I know so many active moms are wondering:

Plus, some lifestyle updates including reducing plastic use at home and what I’m using on my growing belly to support skin hydration.

If you’re pregnant and active (or want to be), this episode will help you feel more confident trusting your body while still chasing your goals.

In this episode of The Pregnant Mother Runner Diaries, I’m sharing what it actually felt like to close out the first trimester while training and growing a human.

This week was a mix of:

I also opened up about preparing for my upcoming half marathon while pregnant and how I’m thinking about effort, expectations, and listening to my body.

OH, and we’re talking doulas.

I share why I had a doula in my first pregnancy, why I 100% plan to have one again, and the exact questions I’m asking while interviewing doulas this time around so I feel supported, informed, and empowered going into birth.

If you’re pregnant, postpartum, or just curious what it looks like to balance running and pregnancy in real life… this one’s for you.
